Microwaves on inverters.
I have a unit with 1500 watt microwave and would like to be able to use it occasionally when dry camping (10 min or less at a time). I plan to use a 2000 watt pure sine wave inverter. Also plan usin...

Takes about 110a (12v) to power our microwave with 2 GC2 batteries using a Xantrex 2000w PSW inverter. We can power the microwave for almost 40 minutes before the batteries are down to 12.2v. Our inverter to battery cable run is almost 13 ft. so we used 4/0 cable. Even at 110 amps we only have a .15v (1.2%) drop.
FWIW, the Xantrex low-voltage alarm activates when the load voltage drops below approx. 11.3v. We've had it down to almost 11.0v (with a 110a load) without it shutting down. Output voltage was down to 109vac at that point. The Xantrex has a very low no-load draw--approx. 700ma.
Pretty pleased with the overall performance of everything. Would love to use 4 GC2's, but no room for 'em in our truck camper.
Got any room under the dinette seating? we had 4 AGM batts under the seating in our TC for 5 years. The 4 batts in a square did not take up that much room.
